Template:ROOTPAGENAME/sandbox
 | __EXPECTUNUSEDTEMPLATE__This is the template sandbox page for Template:ROOTPAGENAME (diff). |
 | This page in a nutshell: Never write {{ROOTPAGENAME|argument}}. Write {{ROOTPAGENAME:argument}} instead. |
 | This template may have no transclusions, because it is substituted by a tool or script, it is used as part of a short-term or less active Wikipedia process, or for some other reason. |
Usage
The magic word ROOTPAGENAME is described at Wikipedia:Magic words#Parser functions. An example of its output is {{ROOTPAGENAME:Template:Example/with/subpages}} → "Example".
This template should never be used, but when someone uses the magic word "ROOTPAGENAME" with a piped parameter, it will prevent breakage. Parameter 1 will be used as the : parameter, other parameters will be discarded.
The page will be added to the hidden category Category:Pages which use a template in place of a magic word (0).
